METHOD AND DEVICE FOR DISTINGUISHING SINGLE TOUCH FROM MULTIPLE TOUCHES

摘要

A method and device for determining a single touch or multiple touches is disclosed. A touch related sensing information with a single zero-crossing is used for determining a pair of values, and the locations of a pair of centroids are calculated depending on the pair of values. The distance between the locations of the pair of centroids can be used to determine whether the number of touches is one or more.
